I installed backgroundrb from http://svn.devjavu.com/backgroundrb/trunk
and there is no problem to start backgroundrb server. but when view the
page which controller requires the worker, I will get the error
“uninitialized constant BackgrounDRb::MetaWorker”. Is this the problem
that I didn’t require the class “MetaWorker” in my worker? How can I
require it?

Can anyone help me? I use Redhat9 OS and rails 2.1.2.
thanks.

There is something wrong with your setup. MetaWorker shouldn’t be even
shown in controller/rails part of things.
Can you post your worker code and how are you invoke BackgrounDRb
worker tasks from rails?

This is my worker definition. I use ruby script/generate worker MakeView
to generate this worker.
class MakeViewWorker < BackgrounDRb::MetaWorker
set_worker_name :make_view_worker
attr_reader :process
def create(args)
# this method is called, when worker is loaded for the first time
process=0
while process < 100
sleep 1
process = process+1
end
end
end
This is the code I used to invoke this worker.
session[:make_view_job]=MiddleMan.new_worker(:class=>make_view_worker,
:args=>{:product_name=>@project_name, :user_name=>@user_name,
:version=>@project_version})
I think this is because I didn’t require the MetaWorker in my worker. Do
you know how to require this worker? I have tried “require
‘backgroundrb’” but “no such file to load” error will be thrown.

I have a feeling that you are mixing up syntax of BackgrounDRb across
its varied releases.
For example, syntax for creating new workers is:

examples are right there in the docs. For example to invoke the worker:
MiddleMan.worker(:foo_worker,“my_secret_worker_key”).async_do_foo()

thanks it works. but when I call this method I will get this error. I
have started backgroundrb server.

Hi,
I have followed this instruction and there isn’t anything related with
TCP or dump.

I set the config/backgroundrb.yml. If the :ip: refers to 0.0.0.0, I will
get the error of can’t dump TCPSocket. If the :ip: refers to the
machine’s IP, I will get No BackgrounDRb server is found running error.
How can I set the IP to avoid this error?
